简要总结
This is a phase 1 open label multicentre study of AZD9496 administered orally in patients with advanced ER+ HER2 negative breast cancer. The study design allows an escalation of dose with intensive safety monitoring to ensure the safety of patients. The study will determine the maximum tolerated dose. In addition, expansion cohort(s) at potential therapeutic dose(s) in patients with or without ESR1 mutations will be enrolled to further determine the safety, tolerability, pharmacokinetics and biological activity of AZD9496

排除标准
- •Any cytotoxic chemotherapy, investigational agents or other anti-cancer drugs for the treatment of advanced breast cancer from a previous treatment regimen or clinical study within 14 days of the first dose of study treatment. Any unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE) grade 1 at the time of starting study treatment with the exception of alopecia. Presence of life-threatening metastatic visceral disease, uncontrolled central nervous system metastatic disease or symptomatic pulmonary lymphangitic spread.

AZD9496 dose escalation and expansion(s)
干预措施: AZD9496 (Drug)
结局指标
主要结局
Safety and tolerability
时间窗: Routine safety assessments, throughout the period that patients receive AZD9496 up to 28 days following discontinuation of last dose of study treatment.
Safety and tolerability in terms of adverse events, serious adverse events (including death) and safety measures: ECG, physical examination, vital signs and laboratory variables. Definition of maximum tolerated dose (MTD) or maximum feasible dose (MFD) by measuring the number of evaluable patients with dose-limiting toxicities.Time frame DLT period 28 days
次要结局
- 4β-hydroxycholesterol concentration in blood(12 weeks)
- Single and multiple dose pharmacokinetics of AZD9496(12 weeks)
- Antitumour activity(every 8 weeks for 24 weeks and then every 12 weeks thereafter until disease progression)
